Description

Vegetative characteristics

When aged men prize is perennial herbaceous plant, the plant height of 15 to 40, rarely up to 80 centimeters reached. The upright, glandular - hairy stems have in the upper part projecting horizontally or upwardly curved hairs ( trichomes ). The obtuse - lanceolate, hairy stem leaves sit against constantly on the stems and are cut notched on the edge, above and entire.

Generative features

The flowering period extends from June to September. In the eye-catching, long aged men inflorescences many flowers are borne. The flower stalks are shorter than the bracts and have glandular hairs. The hermaphrodite flowers are zygomorphic with a double perianth. The calyxes are hairy. The light blue to dark blue - purple petals are fused funnel- shaped, the corolla tube is longer than wide. Are formed capsule fruits.

Differentiation of the subspecies

When Veronica spicata subsp subspecies. spicata ( in Germany this is the only subspecies occurring ) the leaves are dull, the corolla lobes more or less flat and the color is a deep dark blue. The plants remain relatively small with a maximum of around 30 centimeters. When Veronica spicata subsp subspecies. orchid ( which occurs, for example in Austria ) the leaves are sparsely hairy and shiny leathery, the lower corolla lobes are spirally rotated and the color is a light blue ( to purple ). These plants are significantly higher than the nominate race with 30 to 80 centimeters.

Ecology

The spiked speedwell is a Hemikryptophyt and a half rosette plant or herbaceous Chamaephyt.

Pollination is by bees relatives, moths and Diptera. Neighbor pollination is possible.

The capsule fruit act as wind and animal shakers. The seeds are light to germinate. Fruit ripening begins in September.

The distribution area of Veronica spicata is Eurasian- continental, subsp subspecies Veronica spicata. orchid temperate continental - ostmediterran. As localities are Denmark, Finland, Norway, the United Kingdom, Germany, Austria, Switzerland, Italy, France, Spain, Poland, Hungary, the former Czechoslovakia, the former Yugoslavia, Albania, Bulgaria, Romania, Turkey, Armenia, Azerbaijan, Ciscaucasien, Dagestan, the western part of Eastern Siberia, Western Siberia, Kazakhstan, Kyrgyzstan, Belarus, the Baltic republics, Moldova, the European part of Russia, the Ukraine (including Crimea ), and northern Xinjiang specified.

The spiked speedwell grows in sunny dry and nutrient-poor grasslands, on gravel, sand dunes, rocky heads and hem lights, heat privileged bushes. The sites are characterized by dry, nutrient-poor, base -rich, often low in calcium, humus-rich rock or sandy soils. In the phytosociological system Ähriger prize is a Klassencharakterart the fescue steppes and brome - grass ( Festuca Brometea ); the subspecies orchid preference is alternately dry moor grass and semi- arid grassland companies.

The way Veronica spicata is after the Federal Species Protection Ordinance " special protection " and is classified for example, in the German Red List as "vulnerable".

Use

Some varieties of spiked speedwell be used in temperate latitudes as ornamentals in parks and gardens.

Possibility of confusion
